Wheel rear 8.5\" (Halibrand FIA style)

Wheels are manufactured using period correct magnesium sand casting techniques, from our own patterns at the leading motorsport magnesium foundry and machined in house with the latest CNC lathes & mills. Safety beads are incorporated and machined to the industry ‘ETRTO’ standards, as is the rim diameter to ensure correct tyre fitment and sealing. These improvements over the original wheel permit the use of tubeless tyres. Once the machining processes have been completed all wheels are subject to full dimensional inspection on our high accuracy, computerised co-ordinate measuring equipment. Wheels are then finished in the original style black chromate which is a process that helps to arrest the natural deterioration of magnesium. All our magnesium wheels are then subjected to a process of double impregnation and final pressure test which ensures correct sealing and no air loss.
